which is usually expensive. The object of my invention is to providemeans for economizing wood in the manufacture of picture-frames andother articles.

The invention consists in sawing from a plain board or plank concentricor similar figures, and also single figures, with beveled edges, so thatwhen-projected they will develop an irregular surface with close-fittingjoints.

In the accompanying drawing, Figure 1 is a plan of a sawed butundeveloped pictureframe. Fig. 2 is a perspective view of a de' velopedpicture-frame embodying my inven tion. Fig. 3 is a section, through a b,of the undeveloped frame. Fig. etis a section, through c d, of thedeveloped frame; and Fig. 5 is an elevation of the developed frame.

The method of construction is as follows: Any desired pattern is markedon the surface of a board and sawed out on a bevel. The bevel may bereversed when desired, as illustrated in the model and accompanyingdrawings.

What I claim is- The method of manufacturing articles of wood by sawingfrom a board or plank a nest of two or more figures, with beveled edges,in such a manner that when the figures are developed they will wedge,one within the other, forming a rigid body, with close-fittin g joints,substantially as shown and described.
